Two-time world champion Alonso has fought Hamilton numerous times over the past 14 seasons, including as the Briton's team-mate in the ill-tempered 2007 title fight.
Ahead of the Hungarian GP, Alonso responded to Verstappen's FIA press conference outburst by saying: "He is not British so it will always be more difficult for him, so let's see."
Clarifying his stance, Alonso explained: "I have the impression always that when things get a little bit spicy or tense in the title fight, this sport, it is a British environment.
"The teams are British, most of the journalists and media attention, TV crews, everyone comes from the UK.
"Understandably, there is a little bit of preference on the guy from your country that can be competitive and keep winning.
"It is what I felt when I was racing and it seems I was the bad guy in Formula 1 when I was trying to fight against, normally, British guys.
"When I saw the Silverstone thing [the collision involving Verstappen and Hamilton] or when I see Verstappen get some questions et cetera, I understand his position, for sure."
